Fast full file locking for multi-tenancy cloud Java platform

Abstract

On multi-tenancy Java cloud platform, multiple Java applications run in one Java virtual machine instance, which provides high-density Java application deployment and resource control over resource like networking, CPU, thread, etc. But tenant applications run in one JVM still uses traditional Java file locking mechanism provided by conventional Java SE class library, which is based on operating system's file locking infrastructure and is not friendly with cloud environment especially from performance perspective. This idea is to provide aparatus of using Java SE language level locking facility to substitute whole file locking between tenant applications, which significantly improves performance of file locking.

Multi-tenancy Java platform accommodates multiple Java applications in one JVM instance and provides fine-grain control over resource consumption, which significantly improves application density of cloud platform and startup time of Java application. But for the Java developers, one important mechanism for inter-process synchronization is to lock one file between applications, even on multitenancy cloud Java platform this synchronization still has to be done via operating systems' file locking API, such as fcntl, which introduces flexibility over partial locking but also lose performance for the common case of full-file locking.
